Benefits of technology

[0013] Furthermore, the discovery that TR3 is selectively expressed on activated T-cells and the creation of biologically active TR3-specific McAbs offer a viable alternative to using antibodies such as the anti-Fas antibodies, described above. These biologically active TR3-specific McAbs selectively bind ...

Problems solved by technology

However, because TR3-specific McAbs bind to and inhibit the proliferation of activated T-cell...

Embodiment Construction

class="d_n">[0045] This invention provides a composition, comprising a biologically active TR3-specific binding agent that binds to TR3 and inhibits the proliferation of cells expressing TR3. In one aspect, the specific binding agent is a monoclonal antibody or a mimetic of a TR3-specific monoclonal antibody. This invention also provides a hybridoma cell line that produces the monoclonal antibody TR3 μk-1, e.g., the hybridoma cell line deposited under ATCC No. PTA-2659. The monoclonal antibody is selected from the group consisting of: at least one IgG, at least one IgM, at least one IgA1, at least one IgA2, at least one IgE, at least one IgD, at least one IgG1, at least one IgG2, at least one IgG3, and at least one IgG4.

[0046] Further provided by this invention is a composition, comprising a biologically active TR3-specific binding agent that binds to TR3 and inhibits proliferation of cells expressing TR3, wherein the biologically active TR3-specific binding agent inhibits the proli...

Abstract

Biologically active TR3-specific binding agents and methods for their use are disclosed. The biologically active TR3-specific binding agents are useful for inhibiting the proliferation of cells expressing TR3. These biologically active agents are particularly useful for treating T-cell mediated diseases such as graft-versus-host disease, organ rejection, tumor growth, autoimmunity, and inflammation.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit under 35 U.S.C. § 120 of U.S. Ser. No. 10 / 204,419 filed Aug. 29, 2002, which in turn claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60 / 166,583, filed Nov. 19, 1999, the contents of which are incorporated herein by reference into the present disclosure.FIELD OF THE INVENTION [0002] This invention relates generally to biological cell-surface antigens and agents that bind to such antigens. More specifically, this invention relates to biologically active TR3-specific binding agents and to methods for using such TR3-specific binding agents. BACKGROUND OF THE INVENTION [0003] Structural Characteristics of TR3 [0004] TR3 (also known as Apo-3, DR3, LARD, Tramp, and WSL-1) is a member of the tumor necrosis factor receptor (TNFR) superfamily of cell-surface antigens. Some members of this superfamily (e.g., NGFR (nerve growth factor receptor), and CD95 (Fas / APO-1)) have broad ti...
